Why ZnO is an amphoteric oxide?

Why ZnO is an amphoteric oxide?

Answer: Zno is an amphoteric oxide,because it can react with both acids and bases. while in general most oxides only react with acids alone due to its basic nature.

Is zinc oxide a amphoteric oxide?

Amphoteric oxides react with both acids and alkalis to form salt and water. Examples of amphoteric oxides are zinc oxide and aluminium oxide.

Is ZnO basic or acidic oxide?

Answer:zinc oxide show both acidic as well as basic behaviour. Such metals oxides like zn react with both acid as well as bases to produce salts and water are known as amphoteric oxides.

What type of oxide is ZnO?

Zinc oxide is an amphoteric oxide. It is nearly insoluble in water, but it will dissolve in most acids, such as hydrochloric acid: ZnO + 2 HCl → ZnCl2 + H2O.

What are amphoteric Oxides explain with equation of ZnO behaving as amphoteric oxide?

Textbook solution Oxides which react with both acids and bases to give the respective salt and water are called Amphoteric oxides. Example: Zinc oxide, Aluminium oxide. Aluminium oxide, zinc oxide are amphoteric oxides since they react with both acids and bases.

Is ZnO neutral oxide?

1. Neutral oxides: Oxides which are neither acidic nor basic are called as neutral oxides. 2. ZnO is an amphoteric oxide (show both acidic and basic characterstics).

Is ZnO ionic or covalent?

The chemical bonding in ZnO is predominantly covalent but with a significant contribution from ionic bonding. ZnO can crystallize in the wurtzite, zinc blende, and rock-salt structures.

Why is ZnO called an amphoteric oxide give chemical equation also in support of your answer and name another amphoteric oxide?

ZnO (Zinc Oxide) is an amphoteric oxide. Here ZnO acts as a base which reacts with acid (HCl) to form a salt (ZnCl₂) and water. Here ZnO acts as acid which reacts with a base (NaOH) to form a salt (Na₂ZnO₂) and water. Another amphoteric oxide is Al₂O₃ (Aluminium Oxide).

Which of the following are amphoteric?

Many metals such as copper, zinc, aluminum, tin, lead, and beryllium form amphoteric oxides or hydroxides. Complete step by step answer: Aluminum oxide, beryllium oxide, tin oxide, zinc oxide all are amphoteric.

Why is ZnO called an amphoteric oxide?

ZnO is an amphoteric oxide because ZnO is acidic as well as basic in nature. Aluminium oxide is another amphoteric oxide Because it react both with acids and bases to form salt and water .

What are the features of amphoteric oxides?

What are Amphoteric Oxides? Amphoteric oxides are oxides, which behave as both basic and acidic oxides. Amphoteric Oxides contain the features of acidic and basic oxides as well that neutralize both acids and bases. This is the simple amphoteric oxides meaning.

What happens when ZnO is mixed with water?

ZnO reacts with hydrochloric acid forming zinc chloride and water. ZnO + 2HCl = ZnCl2 + H2O. With sodium hydroxide, it forms sodium zincate and water.

How does ZnO affect the melting point of ceramic?

Ceramic industry. ZnO affects the melting point and optical properties of the glazes, enamels, and ceramic formulations. Zinc oxide as a low expansion, secondary flux improves the elasticity of glazes by reducing the change in viscosity as a function of temperature and helps prevent crazing and shivering.
